从海洋油气勘探周期谈探矿权登记管理

Discussing Exploration Right Registering Management from Rules of Offshore Oil and Gas Exploration Cycle

油气勘探普遍存在周期性规律,勘查工作量部署遵循勘探地质评价各个阶段的不同特点。南海西部近海原油勘探周期为4~5年,高温高压天然气勘探周期近10年,深水天然气勘探周期更超过10年;天然气勘探周期长、费用高。现行油气探矿权审批登记颁发勘查许可证首次有效期为3~7年,每2年延续一次,并以每2年的实物勘查投入作为延续登记的考核标准,不符合海洋油气勘探周期的规律,不利于天然气勘探健康发展。建议:(1)延长探矿权有效期;(2)整体考核持证期内勘查投入。

Oil and gas exploration normally runs in cycle.Therefore,exploration workload deployment should abide by specialties featured different exploration geological evaluation phases.Offshore crude oil exploration cycle in western South China Sea is 4-5years.High temperature and high pressure gas exploration cycle is nearly 10 years.Subsea gas exploration cycle is more than 10 years.Gas prospecting has long cycle and high cost.Current approval and registration system for oil and gas exploration right issues exploration licenses with first validity of 3-7 years,extended every 2 years,taking material objects input in exploration as standards of extension.This system does not fit in rules of offshore oil and gas exploration cycle and goes against sound development of natural gas exploration.Suggestions:(1)extending validity of exploration rights;(2)examining overall exploring input during validity.
